Over the past two decades, the United States government conducted detailed analyses of the potential of a biobased national energy strategy that produced four unified studies, namely the 2005?2016 US Billion-Ton Study and updates. With each effort, better perspective was gained on the biophysical potential of biomass and the economic availability of these...

The report includes descriptive highlights and tables of area, numbers of trees, biomass, carbon, volume, growth, mortality, and removals. Most sections and tables are organized by forest type or forest-type group, species group, diameter class, or...

This report presents a summary of the most recent inventory of New Mexico?s forests based on field data collected between 2008 and 2014. The results presented here summarize a complete cycle of New Mexico?s forest inventory, or 10 years? worth of data collection, whereas the previous report was based only on 9 years? worth of data collected under an accelerated...

This report presents a summary of the most recent inventory information for Montana's forest lands. The report includes descriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, and removals.

This report presents a summary of the most recent inventory information for Idaho's forest lands. The report includes descriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, and removals. Most of the tables are organized by forest type, species, diameter class, or owner group. The report also describes inventory design,...

A challenge in the development of renewable energy is the ability to spatially assess the risk of feedstock supply to conversion facilities. Policy makers and investors need improved methods to identify the interactions associated with landscape features, socioeconomic conditions, and ownership patterns, and the influence these variables have on the geographic location...

This report presents a summary of the most recent inventory information for Nevada?s forest lands. The report includes descriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, and removals. Most of the tables are organized by forest-type group, species group, diameter class, or ownership. The report also describes...

This report presents a summary of the most recent inventory of Utah?s forests based on field data collected from 2003 through 2012. The report includes descriptive highlights and tables of area, numbers of trees, biomass, volume, growth, mortality, and removals. Most sections and tables are organized by forest type or forest-type group, species group, diameter class,...

Renewed interest in non-native Eucalyptus species for planting in the southern US has been spurred by projections suggesting they are more productive than the widely cultured Pinus species, by warming temperatures, and by attempts to identify frost-tolerant species as well as developing genetically modified ...

The 20th century was marked by rapid growth and increased prosperity in the world. By 2020, the world?s energy consumption is predicted to be 40% higher than it is today, even in the presence of the global 2008/2009 economic recession (Energy Information Administration 2009). Key sources of oil for U.S. markets are located in complex geopolitical environments that...

Logistic regression models combined with Bayesian inference were developed to predict locations and quantify factors that influence the siting of biomass-using facilities that use woody biomass in the Southeastern United States. Predictions were developed for two groups of mills, one representing larger capacity mills similar to pulp and paper mills (Group II...

The impact of the trucking transportation network flow was modeled for the southern United States. The study addresses a gap in existing research by applying a Bayesian logistic regression and Geographic Information System (GIS) geospatial analysis to predict biorefinery site locations. A one-way trucking cost assuming a 128.8 km (80-mile) haul distance was estimated...

Short rotation woody crops (SRWCs) are key renewable feedstocks for the emerging bioeconomy. A critical step in developing a bioeconomy is defining suitable regions for commercial SRWC activities. The goal of this study was to estimate the obtainable yield in mean annual increment and economic returns on investment for Populus deltoides and Populus hybrids for the 33...

Questions related to economics figured prominently in the priority information needs identified in the 1997 Tongass Land Management Plan. Follow-on studies in economics werc designed to improve understanding of aspects of the competitiveness of the Alaska forest sector, links between Alaska timber markets and other markets as evident in prices, and the relationship...

Factors influencing invasive taxa may change during the course of an invasion. For example, intraspecific competition is predicted to be more important in areas with older stands of dense monospecific invaders than at the margins of an invaded range. We evaluated evolution in response to predicted changes in competition by comparing the intraspecific competitive...

The use of renewable resources is important to the developing bioenergy economy and short rotation woody crops (SRWC) are key renewable feedstocks. A necessary step in advancing SRWC is defining regions suitable for SRWC commercial activities and assessing the relative economic viability among suitable regions. The goal of this study was to assess the potential...
